TLE-1F MiniStar1 Universal Fit Flange Mount LED Lightbulb Upgrade

As a senior facility electrical engineer at a fortune 500 company, I use a Ray-O-Vac , 2 D cell yellow magnet base industrial rated flashlight daily. As a result the batteries don't last very long.. Here's why.. Years ago, standard dry cell batteries used a PR-2 incandescent bulb.. drawing 400-500 milliamp current...Then came alkaline batteries for longer life...Ok thats good... then came krypton bulbs for increased brightness.... however we increased the current flow up to 600 m.a.... and life is short again.. Replacing batteries weekly gets very expensive....With the TerraLUX LED bulb, 50 lumen , you down to 250 m.a. and brightness about the same or slightly better than the PR-2 or Kripton incandescent bulbs... Unfortunately, they are 4 times the cost, however, hopefully, the longer life will off set the cost.. I tested many manufactures bulbs of various lumen brightness, in dark rooms, and measured the current flow...In my opinion, and our electricians, we now all use this LED bulb exclusively....for improved lighting, longer life, and total cost reduction...in all our plant maintenance flashlights ...The LED blue color span ( vs. yellow with incandescent bulbs) does bother some folks , however, this TerraLUX has no center dead spots, and appears less blue than some other manufactures bulbs or lumen brightness we tested......P.S. Using 75 or higher lumens gets you greater brightness, however current flow is back up to 500 m.a. ... resulting in short battery life .... Next time you in a big box store and see 2 D cell camping flashlights claiming 300 lumens brightness you can shine to the moon with is great...but its overkill for daily up close general use... I dare you to turn on one of these flashlights, then come back in a few hours... ... batteries dead..

Installed it in my Ryobi. Did not work. Thought it might be the light itself. Had purchased another that came in after this one. Installed one of those-it worked. Might be a bad bulb. Too much hassle trying to return it for credit or a replacement. Just take the bite.

This led "upgrade" for 2-6 C/D cell flashlights is very bright in little to no light locations I gave it 3stars only because the light beam does not project that far great for home or automotive use but not for applications where you need light in far places like security and police

Bulb will only light if the The bottom tip of the bulb goes to the positive (+) contact of the batteriesMost 6V lantern battery Flashlights put the negative (-) contact to the base of the bulb. In this style of flashlight, (which is what i got it for) the bulb WILL NOT LIGHT.It should work in most flashlights using D cells, but unless you have at least 4 D batteries, it won't be very bright.

This is a basic LED conversion module for C or D flashlights that take a flanged bulb. There is also a version available for flashlights which use screw in bulbs. Use is not restricted to Maglite flashlights so the product description needs to be corrected. The Terralux web site indicates the general flashlight suitability of this LED bulb.In the two flashlights I installed it in, a 2D cell stainless steel Garrity and a 3D cell Kel-Lite it outputs more light than the Krypton bulbs that it replaced. Results will depend on the flashlight the module is installed in as the 2D Garrity flashlight is brighter than the 3D flashlight. I suspect a combination of reflector design, switch resistance and possibly other factors are involved.I swapped LED modules between the flashlights and tried brand new batteries in the 3D light with the same results so this result is not related to battery condition or variations in LED bulb output.The resultant beam in both lights has a center area that is much more even in light output than with a incandescent bulb. The light is yellower than from a Maglite 3W LED conversion module and not as bright but the Maglite one will not fit either light converted due to the larger base diameter and no notch cutout in the flange of the Maglite LED bulb as required by many flange bulb flashlights.Overall a worthwhile conversion but not comparable in output to many of the high intensity LED lights on the market. Not tested yet but it should provide much increased battery life compared to standard flashlight bulbs and not fail if the light is knocked over or dropped as incandescent bulbs do. Not tested in more than a 3 cell flashlight though it claims to work in any 2 to 6 cell light.

I have had my 2-Cell Mag-Lite for years and have held onto it because I love it. At least I did. Call it a guy thing, but when 5watt V8 LED headlamps from China at a fraction of the cost outshined my Mag-Lite, I had to find a way to change the situation. Read about these LED bulbs that worked and decided to chance it. Went with the lower wattage one for two reasons. One, that it cost less and two, reviews stated it was not significantly dimmer than the TLE-6EXB one.Well, it swapped out in less than a minute and worked like a charm. I then challenged the head lamp by staring into the lights - by the way, don't do this. Just not smart and not scientific. Both hurt and both were bright. So I decided to shine them against the wall. Hah! No longer weaker and dimmer.I cannot speak to lumen ratings, but it did breathe new life into my Mag Lite . . . and just for kicks I did end up buying the TLE-6EXB for my 3-Cell and pit them against each other. The 3-Cell appeared a bit brighter and whiter, but not significantly so. (Not that I did not believe the reviews, just had to give it a go myself.) Especially when you focus the beam: a much tighter and cleaner focus than Mag-Lite bulbs it came with.

i bought this bulb for use in my 6 cell maglite and it isn't even half as bright as the bulb that came with it it was nothing short of a complete waste of my money I would not recommend this bulb made a slight difference in my Duracell 2d flashlight but worthless for what i wanted
